I was wondering if there was any way to figure out what types of matches a map can be used (ie. DeathMatch, RamboMatch, ...) without opening Soldat or a map editor

Is there any way to do this?

easily, by the prefix contained in the name:

Deathmatch/ RamboMatch/ Teammatch / PointMatch:

Anything but ctf_, inf_, or htf_

Hold The Flag:
htf_

Capture the Flag:
ctf_

Infiltration:
Inf_

Of course you can load any of these maps in the gamemodes and if they contain the right spawn points they can be played in all modes

You're wrong there. If a map is missing a SP it'll just smart-position its own SP temporarily for the match (if it's missing a Rambo Bow or something it'll try to put it around the middle of the map, etc.)
