Answer 1

So you want to inside a proc check if a #temp table exists, based on a table name that you have in a parameter to that proc? If so, see below. You have to prefix with the database name tempdb in your check with OBJECT_ID():
CREATE PROC p #t1 sysname ,#t2 sysname AS IF OBJECT_ID('tempdb..' + #t1) IS NOT NULL PRINT '#t1 exists'
IF OBJECT_ID('tempdb..' + #t2) IS NOT NULL PRINT '#t2 exists' GO
CREATE TABLE #t(c1 int)
EXEC p #t1 = '#t', #t2 = '#doesntexist'
