The phrases appear to be in Polish. A straightforward interpretation is:

• "ile" = how many
• "lat" = years
• "na" = on/for
• "posla" = deputy (poseł)

If you’re asking how old one must be to become a deputy (posła) in Poland, the typical answer is: a candidate must be at least 21 years old to become a member of the Sejm (the lower house). For senatorial candidates (Senat), the commonly cited threshold is 30 years old. Note that eligibility also includes other conditions such as permanent residence in the constituency and not having disqualifying criminal convictions, depending on the specific office and jurisdiction. If you meant something else by those words, please share a bit more context and I’ll tailor the answer.
