Details on morning greetings
My friend says to me （我的朋友说了）: “老乔，早上好。”

Can I say （我可以说吗）: “是啊。。太早吧” OR "是啊。。但是太早吧” OR ”是啊。。有太早吧“

I'm trying to be a little funny to my friend, saying "Yes it's a good morning - but it's too early, right?" Are any of these examples correct, or natural sounding?

Answer

You can say "早! —— 嗯, 还真早." 
The first 早 means "morning", which is a more informal greeting than 早上好. The second means "early".

Answer

the hello you intent to show in a funny way just not quite there..

xiaokaoy has given a good choice, or maybe you can exaggerate a little bit in the adjective：是啊，的确很早（yes, good mornig indeed）

Answer

早啊，不过（但是）太早了吧。I think this one can express what you meant, and your sentence is OK, but it is not very smooth.
