【分析】
转换一般疑问句需遵循核心规则：1. 句中有be动词时，直接将be动词提至句首，第一人称变第二人称，其余语序不变；2. 句中是实义动词时，根据主语人称和时态借助助动词do/does，主语为第三人称单数用does，其余用do，同时实义动词变回原形，第一人称变第二人称。结合每个句子的主语和动词类型，按规则转换即可。
【解析】
1. 句子含be动词is，将is提至句首，其余部分调整，得到：Is he a good boy?
2. 句子主语是I，实义动词go，借助助动词do，I变you，得到：Do you go to bed early?
3. 句子主语是I，实义动词短语get up，借助助动词do，I变you，得到：Do you often get up late?
4. 句子主语是we，实义动词watch，借助助动词do，we变you，得到：Do you often watch TV?
5. 句子主语是he（第三人称单数），实义动词makes，借助助动词does，makes变回原形make，得到：Does he often make a mess in his room?
