Beam or Arc really depends on your room size and how loud you want things but as said they are all three front channels.
If you put Fives at the front of the room you have two options, as surrounds where you will get little sound from them and that usually won’t include what you get from the front three channels or as a stereo pair room grouped with the Arc/Beam when the sound will be delayed due to the networking. Neither is going to sound any good.
A 2.0 Five stereo Room, or maybe 2.1 using Ones and a Sub/SubMini will sound great for music but not for the TV.
A 3.0, 3.1, 5.0 or 5.1 With Arc/Beam, One SLs and possibly a Sub or MiniSub will be good for TV.
An Amp and your choice of passive speakers will get you 2.0 TV sound with an attempt to make it sound like you have a center channel by manipulating the two speakers. You can add surrounds directly or use another Amp and your choice of speakers.
