How to write regex which find word (without whitespace) that doesn't contain some chars (like * or #) and sentence also (like level10 or level2 - it should be also regex - level[0-9]+). It will be simple for chars excluded ([^\\s^#^*]+) but how to exclude this 'level' example too ?

I want to exclude chars AND level with number.

Examples:
weesdlevel3fv - shouldn't match because of 'level3'
we3rlevelw4erw - should match - there is level without number
dfs3leveldfvws#3vd - shouldn't match - level is good, but '#' char appeared
level4#level levelw4_level - threat as two words because of whitespaces - only second one should match - no levels with number and no restricted chars like '#' or '*'
