I tried below code but it gives all records
grep -E '[a-zA-Z0-9]+' temp.txt
I need only those records which contains either letters or number or + sign. If any record contains any other characters then it should be discarded. Record number 3 and 5 should not come in result:

Welcome to the U&L SE. There's only one entry in your question that has a the '+' character in it. Is that the only type of pattern (6 digits followed by a '+') or do you have other patterns you want to look for?

Every line there contains "characters "; which ones exactly do you want to include or exclude?

Rather than provide relevant details in comments, you should edit the question to improve its quality. I came across this question because it had been nominated for closure due to its lack of clarity. I voted to keep it open and edited it for you -- but you should really do this yourself.

Remove any line that contains a character that is not (a letter or number or +):
grep -v '[^[:alnum:]+]' file

You're missing the + in your character list. The plus after the [...] is the quantifier (1 or more of the before mentioned character group).
Also you must enclose it in ^ for start of line and $ for end of line, as otherwise you will also match parts of each line, e.g. 278178 from 278178##.
Try this,
grep -E '^[a-zA-Z0-9+]+$' temp.txt
