Les paras is a short for 'les parachutistes' - understand paratroopers, rather than people skydiving as a sport or passion. "allez les paras" means then 'go the paras, hooray for the paras'
Allez les gars - go on lads
'Allez les bleus' means 'go Blues, hooray for the Blues.' Les bleus is the nickname of the national French sports teams (especially football) because of the colour of their traditional jersey.
It means I don't like The Blues (French national football team). This is a very un-French thing to say - normally they would say "Allez allez les Bleues" (Come on you Blues)
allez les rouges!
To say "Go Saints" in French, you would say "Allez les Saints." In this phrase, "Allez" means "Go" and "les Saints" translates to "the Saints." The verb "aller" is conjugated to match the command form, and "les" is the plural definite article used before "Saints."
allez les Panthères !
Allez les diables !
Go on , the red (I suppose it should be in the plural - Allez les Rouges - Go on the Reds)
Les Maple Leafs de Toronto. It's a sports team, so you wouldn't do a full translation (les feuilles d'erables de Toronto).
Les informations mean 'the information' in English. In the context of watching TV, les informations are 'the news'.
Les trains means "the trains" in English.
"Les souliers" means "the shoes" in English.
