Let me be sure I understand. The first of your two issues is that the fans ALL blow air OUT of the case and you want the front ones to suck air in instead. That is the right way. Later you have posted a photo taken from the INside of the case showing the front fans, and that appears to show that their lighted rings are facing the INSIDE of your case, towards the back. Is that right? And those are the fans that blow air from the INSIDE (where the rings are visible) through the front panel to the outside?
If that is the situation, then this is much simpler. Those fans simply are installed backwards! Each should be un-installed from the front panel where they are held in place by screws, turned around, and the screws re-installed. When you do this, turning the same screws into the holes of the fan frame may well feel harder to do - those holes have never had screws in them to cut new threads. But they DO screw in. This would place the LIGHTED rings of each fan facing toward the FRONT of your case so they can be seen clearly from outside, AND change the direction of air flow to intakes.
Now, there will be issues involved here. Please check these details because the construction of these fans is not standard. "Standard" ARGB lighted fans have TWO separate cables coming out of each fan. One of these ends in a standard 4-hole female connector about 3/8" wide that plugs into a mobo fan header. The other ends in a wider connector also female with three holes, but it looks like it had 4 with hole #3 filled in. This plugs into a mobo lighting header. YOUR fans, however, each have two sockets on their frames on opposite sides, and come with little connector blocks with 7 pins on each side. It apears the intent is that you use those blocks to connect from the "Power In" socket on one fan to the "Connect" socket of the next so that all three fans are connected together in one chain. The web page I found for these fans says the sockets and connectors distribute power and control of BOTH the fan motors and the lights. Then, I assume, there is a single cable that goes from the first fan in this chain to the "Hub" as you call it. You indicate that this cable has TWO arms, and the second goes to somewhere on the mobo. And lastly you say there is a connection from the PSU to the "Hub". Is that all correct?
If that is correct, there is one thing missing. The fans need both power and control signals for the motors AND the lights. Power for both items probably comes from the PSU through the Hub. Control signals for both the motors (for speed)and the lights (for display control) are needed from different mobo headers, but you indicate that there is only ONE cable going to the mobo. So to where? Does it have a connector about 3/8" wide with 4 holes, and two ridges running down the side of it? That would plug into a mobo header called SYS_FAN or CHA_FAN. OR, does it have a wider connector with 3 holes spaced for 4 holes, but with one blocked off? That would plug into a different mobo header for lights. But as a matter of fact, you have not told us what mobo you have. Tell us which maker and exact model mobo so we can look up its manual and advise. For example, if your mobo has a lighting header of the correct type, you may need to connect to that header to get control of the displays; if no such header, you may need a different control signal source.
Anyway, to return to the fan re-mounting idea above, the little connectors between fans makes it slightly trickier. You may need to remove the mounting screws for all three front fans, temporarily disconnect the cable from the first fan to the Hub, turn around the entire block of fans and re-mount them, then re-connect the cable. That would address your first issue. The info on how and what connections there are to your mobo will help with the lighting control issue.
