"Tengas" is second person singular subjunctive of "tener," meaning "have." in other words, the subject is "you," one person, and there is some aspect of hope or uncertainty about the sentence. Not a statement "you have such-and-such" but it could be "* hope you have...."
It is a command which means "have". In a sentence you would say something like "Tenga tu tarea" which means "have your homework"
"tenga" means "take it" or "have it" or it depends how you use it.. if you say "tenga el lapiz" your'e saying "take the pencil"
This looks like a badly translated sentence from English to Spanish, probably from the English: "Have a nice nap." But you would never say "que tenga una buena dormir," which literally means "may you have a nice sleep." More likely in Spanish you would say simply "Duerme bien" which means "Sleep well."
"quidera" is not a Spanish word.

I have = tengo Tenga Tengan Ten Tened ... ...
