Need suggestions against e4, any gambit variations of any opening?
A Gambit style repertoire for Mad chess players

Besides the fantasy caro, everything you mentioned is pretty dubious. Just stick to solid openings and central play.

no
1.Nf3 and then :
- Tennison gambit, do not go for the trap but the way Keres play it
- Halloween gambit
- Sicilian Wing gambit
Englund, 1. d4 e5 2. dxe5 Nc6 3. Nf3 Qe7 4.Bf4 and now not immediately Qb4+ but first f6
Scandinavian icelandic Palm gambit and Portuguese

If you want to play gambits, then against e4 you have to play e5.
There's not a lot of "mad" gambits that are good, and some of them are even losing. But you can try something along the line of Jalalabad Sicilian(essentially a better Stafford), Latvian gambit or even Elephant gambit(not recommended though).
In general it is hard to control the pace of the game with black. Therefore, instead of trying out mad gambits with black and take massive risks, you should probably play some aggressive openings that are not completely mad.
Though at the end of the day, you are the one controlling how you want to play.

For example Schliemann in the Spanish, h6-g6/g5 set ups in the Italian are all good options that are playable, although not objective best.

Ha. You've mentioned most of the openings I like to play! As white, I like King's Gambit and Smith Morra. As black I play Scandinavian and Budapest. For Scandinavian, I play 2. ... Nf6, rather than moving the queen. GM David Smerdon has a phenomenal book on the Scandinavian that I strongly recommend.
Against computers or top players these openings may not work. But I'm not a great player, and at my level all of these gambits can be very effective. They all have the very real advantage of forcing your opponent to play your game rather than theirs.
I haven't found anything really good or fun to play against the Caro Kann or French. ...

Guys recommend second tier gambits, most of the gambits recommended are outright losing.
What about the following:
- Alien Gambit
- Benko Gambit
- Queens Gambit
I want opening suggestion and responses which fits the following criteria.
Gambit should be playable, don't care for loss of little objectivity.
It should be mad enough (Openings such as Kings Gambit)
So far the choices are:
Kings gambit, fantasy caro gambit variations, milner barry, smith morra (although open sicilian mad variations also there).
Against e4 - No idea.
Against d4 - Budapest, or maybe von scharra
