Answer:
The Radical Republicans wanted: To establish the economic and financial stability of South but at the same time, wanted to punish confederate leaders. They were also radically against slavery wanted to abolish it as soon as possible.
Moderates (national unity party) wanted: Moderates wanted to reestablish the economic and financial stability of Southern States but also did not believe in harsh punishments for Confederate leaders. While they wanted to provide freedom to slaves, they shied away from giving equal rights in every sense.
Democrats wanted: To NOT help in the reconstruction efforts of the South. They were also pro-slavery and did not believe in freeing slaves.
Explanation:
The Radical Republicans were an informal group within the Republican party which called for an immediate abolition of slavery without any compromise. It was made of religious men who believed slavery was against God's will and held very strong views.
The National Unity Party was a name used by the mainstream Republic Party e.g. the likes of Johnson. They had a more moderate vision of how to get the country back on track. This was a 'moderate' view with a lot of opposition from the Congress as well as the general public.
The Democrats, acting as an opposition party, was pro-slavery and did not want to see an end to the practice. At the same time, they believed that the South should be punished and reconstruction efforts should be minimum,.
