PRIMARY TYPEDEFINITION
Open
Semi-OpenVoters are allowed to choose which party's candidates they are nominating, but they must either publicly declare their selection or register with the party in whose primary they are participating. ~ ThoughtCo.
Open to UnaffiliatedUnaffiliated voters are allowed to participate in any party primary they choose, but voters who are registered with one party are not allowed to vote in another party’s primary. ~ National Conference of State Legislators
ClosedOnly voters who have registered as belonging to a particular political party can vote. ~ US Legal
Semi-ClosedParties may choose whether to allow unaffiliated voters or voters not registered with the party to participate in their nominating contests before each election cycle. In this type of system, parties may let in unaffiliated voters, while still excluding members of opposing parties. ~ National Conference of State Legislators
Top Two
Also called Jungle or Blanket Primary, all candidates are listed on the same ballot. The top two vote-getters, regardless of their partisan affiliations, advance to the general election. Any registered voter may participate in the primary and vote for any candidate, regardless of his or her partisan affiliation. ~ Ballotpedia
Other

Louisiana - all candidates run on the same ticket on the general election date. If no candidate receives over 50% of the vote, then the top two vote getters face a runoff six weeks later. 


Nebraska - all state legislative candidates run on the same, non-partisan primary ballot

 

Ohio - nonpartisan registration - there is no option to affiliate with a political party on the voter registration form. All registered voters choose one party's ballot to cast their vote in the primary. This choice designates the voter's party affiliation. An unaffiliated voter may decide not to participate in either party's primary and will be given the amendments/referendum ballot only.
