Yes, First one is S

Second one could be Sa, or the symbol of Protection.... but it would be a long shot...
Sa =

Bird is "oo" or "o" or "u"

and the last one... IDK... it could be a perversed version of "was" or the symbol for the sceptor of someone in power.
was =

Like I said, they look completely different, but those are the closest I could find for them... I know that the Bird is "oo" and the first one is "S", I just don't now about the rest.
